Spondoolies-Tech vs Bitmain for a larger operation?

[alh]

Got the SP20s today. NICE units.

I'm going to give them a few hours to burn in before I start looking at the numbers.

I see why people say that 1.7TH isn't realistic. Mine are steady at 1.55 after an hour with the standard settings. I'll play with those a little later in the day when I have time.

I'll say this though, the QUALITY of the boxes is superior in every way.

This is also where your cost minimization come in. Everything I have read indicates that the last 200GH area really pretty expensive to obtain in terms of power cost. There are multiple SP20 threads, even one that includes efficiency plotted again hashrate. The higher the speed, the higher the $$$/GH.

yes if I recall he has dirt cheap power 4.5 cents  so if he gets 770 watts for  1350  and 1000 watts for 1550  even though he is using 230 watts for 200gh he may be better off at 1550gh.

I just ran numbers at :

0.045 cents a kwatts
230 watts for 200 gh
diff of 41.27
btc at 223 usd 

he will make .29 cents  a day more then if he stays at 770 watts and 1350gh

That's exactly what I'm tuning for right now. I'm going to let it eat tonight and play with it tomorrow when I have more time to dedicate to it.

Hey gang. I'm new here.

Quick background: My company has been in the financial tech space for 10y and currently processes about 500M transactions annually in the Gift/Loyalty space. We have an interest in linking crypto currencies, and that's what brings me here.

I have a friend with a company that has a 500 TH/s operation using the Antminer S5. We're looking at building something similar in the coming weeks, but after I started researching, I came across the Spondoolies-Tech SP20.

Looks like bang-for-buck has the SP20 in the lead, but I didn't know what else I should be looking at. I've tried searching here, but it's currently disabled.

Can anyone point me in a good direction?

I've ordered 5 S5s and 5 SP20s to compare the two.

Pros/Cons?

Thanks for the help. It's appreciated.

Both are good options.

I have many of both.

If is my desicion today I will get the SP20 for a large install because sometimes S5 stop working and require a manual reboot.

If SP20 underclocked is a bit more efficient also but nothing significant and if your electricty cost is low you can get 1.7 TH from SP20 compared to the 1.3 TH you can get with a S5 OC.

Might be a bit of a moot issue now anyway, seeing as they're sold out

We are Happy to announce that the SP20 has sold out.

Right, timing is not so good since SP20 is discontinued and S5 is unavailable as well.
Issue a massive call for used machines? will probably have to pay premium.
